[Q] Sprint M7 cant select GSM/UMTS, it reverts to last used mode
Greetings, im sure this is a common issue that ive seen, i received a HTC One M7 Sprint, it is sim unlocked BUT... can't select GSM/UMTS mode, it reverts to last used mode (if lte/cdma was selected and I choose gsm/umts, it reverts to lte/cdma...)
Is a NV problem, or radio problem? can be corrected?
Thanks a lot!
